1 Claim.

This invention relates to illuminating devices and particularly toreading lamps.

The primary object of the invention is to provide a reading lamp with anauxiliary light which is suitable for special types of illumination.

Another object is to provide such lamp with an independentallycontrolled spot-light which is swivelly connected to the main lightstandard.

These and other objects and features of the invention will becomeapparent from a' study of the following description and claim togetherwith the accompanying drawing in which like parts are designated by likereference characters and wherein:

Figure 1 is a side elevation of a floor lamp showing comprehensively theinvention;

Figure 2 is an enlarged view partly in section showing the assembly ofthe lighting units;

Figure 3 is an enlarged view partly in section of the spot-light swivelconnector; and

Figure 4 is an enlarged view partlyin section showing the constructionand assembly of the spot-light shell and cap members.

Broadly this invention consists of three main parts. There is first, thebase or support member l; next, the upper or general illuminating means,sometimes referred to herein as the first or primary lighting member 20;and finally, the spot-light which is also referred to as the secondarylighting member 30. Each of these parts will be described in detail andin the order just set forth. In general the particular lamp constitutingthis invention has the appearance of the adjustable lamp illustrated anddescribed in the United States Design Patent No. 117,672 granted to M.E. Kraft on November 21, 1939.

The illustrated support or base member ID consists of a conventionalvertical tubular shaft or portable standard |2 which is suitably mountedon the base It. Attached to the top end of the standard I2 is a hingedbracket or supporting arm l3 on which there is mounted the primarylighting member 23. The supporting arm l3 has a hinge or fixture joint Mof the type shown and described in the United States Patent No.2,088,321 which was granted to Vermont Follet on July 27, 1937. Thisjoint I4 permits the lighting units to be moved or extended sidewisewith respect to the standard |'2. The character 20a of the Figure 1indicates in broken lines an alternate position of the lighting members.The primary lighting member 20 consists of a single illuminating elementand socket cover 2| and a conventional shade 22 mounted thereon. As thisportion of the lamp is well known to the art, further detaileddescription will be dispensed with.

The secondary lighting member 3|! is similarly attached to the bracketI3 but hangs down just below the primary lighting member 20 and dependsfrom the bracket arm T joint |5.

Specifically, the lighting member 30 consists of a somewhat conicalmetal case or shell 3| inside of which there is mounted an electricsocket 32 and a small electric light bulb 33.

The broad or open end of the shell 3| is closed with the metal capmember 34. This cap member 34 is provided with a condensing lens 35which is aligned with the light bulb 33 so that the rays emanatingtherefrom may be concentrated and focused on some particular point. Thelens 35 is mounted in the cap member 34 by conventional means, whichmeans are shown in the drawing by the ring 36.

The cap member 34 is made to removably engage the shell 3| so that thebulb 33 may be inserted, removed or replaced. For that reason, the brim37 of the cap member 34 is flared outward slightly so as to neatly butnot tightly engage the lower brim of the shell member 3|. The shellmember 3| is, at the surface of contact'with the cap member brim 31,provided with a plurality of small outwardly extending ears or tabs 38and the cap member 34 is similarly provided with dents or holes 33 whichengage the tabs 38 and keep the shell and the cap members in unitedrelation. This particular construction is similar to that found onconventional twopiece brass shell electric light sockets, and the twounited parts may be easily separated by simply pressing the shell 3|inward at some point and disengaging the tabs 38 from the holes 39.

The top or more pointed end of the shell 3| has a central hole throughwhich a small threaded nipple 4| passes and secured thereto. Theelectric socket 32 is threadedly mounted on this nipple 4|. The outer orupper end of the nipple 4| threadedly engages the swivel connector 40which connector permits the spot-light 30 just described to be directedat an angle away from the perpendicular. In the Figure 2 of the drawingthe character 39a indicates an alternate angular position of thesecondary lighting unit 30.

Ihis swivel connector is slidably mounted on a rigid ball-like member 42which is firmly attached to the T joint I5. Ball-like members of thistype are well known in the lighting fixture art but for a clearerunderstanding of this invention it may be described briefiy as follows.An inverted cup-like member 43 has a hole therein which secures andslidably engages the top portion of the ball 42. An upright cup-likemember 44 has a threaded hole therein which engages the top or outer endof the nipple 41. The top outer edge of the cup-like member 44threadedly engages the lower inner edge of the inverted cup-like member43. Inside of the two cup members 43 and 44 there is a bushing 45 whichcontacts and slides on the bottom half of the ball 42. The bushing 45 isheld in relatively tight engagement with the ball 42 by the expansionspring 46. This construction is clearly shown in the Figure 3.

The two illuminating units 20 and 30* are suitably wired and haveindividual control switches thereon so that each may be turned on or offindependently of the other. In the drawing the electric wires orconductors are indicated by the character l6 and the control switchesfor the primary and secondary lighting members are indicated by thecharacters 23 and 41 respectively.

It will now be clear that there is provided by this invention anilluminating device which accomplishes the objects herein set forth.While the invention has been illustrated in its preferred form and whileit has been described in certain specific terms and language, it is tobe understood that the embodiment of the invention as illustrated anddescribed is suggestive only and is not to be considered in a limitingsense. It should be further understood that as there may be other formsor adaptations of the invention those modifications are considered to bewithin the scope of this invention as no limitations upon it areintended other than those imposed thereon by the breadth of the appendedclaim.

We claim:

A combination lamp and spot light comprising in combination, a portablesupporting standard, an arm member attached to the supporting standard,a lamp member having a light difiusing shade mounted on the said armmember and projecting upwardly therefrom, and a spot light including alight concentrating lens mounted on the said arm member and dependingbelow the said lamp member, the said arm member including a swivel meanscapable of retaining the spot light in fixed positions, and alsoincluding a hinge member permitting the movement of both the said spotlight and the saidlamp member simultaneously.
